Abstract: 1405613 Shearing SIEMAG SIEGENER MASCHINENBAU GmbH 19 July 1972 [21 Aug 1971] 33684/72 Heading B3W A device for severing wire, for use in a coil forming station, comprises a vertical shaft 2, at least three guides (four guides 7 as shown) pivotally mounted to pivot about axes parallel with the central axis of the shaft between a first, broken line position in which they do not occlude the shaft and a second, full line position in which they define an aperture, entraining wire dropping through the shaft as they move from the first to the second position to guide it into the aperture, and a shear 13, 14 near the aperture. The plates 7 and levers 10 are respectively pivoted by hydraulic cylinder units 8 and 11, the levers 10 passing below the plates 7. One lever 10 carries the fixed blade 13 and the blade 14 reciprocated by a fluid cylinder 15, the edge of the blade 13 being aligned with the edge of one plate 7 in its second position. In operation, wire is dropped through the shaft 2 on to a coiling mandrel (3), Fig. 1 (not shown). When the coil reaches a predetermined weight or size fluid cylinders 8 are actuated to move the plates 7 to the second position. Wire continuing to be delivered to the shaft 2 forms a coil on the plates 7. The cylinders 11 are actuated and the levers 10 sweep along the slot 12 between the plates to centre the length of wire joining the coil forming on the plates to the coil on the mandrel, which length is then severed by the blades 13, 14. In an alternative embodiment, Fig. 3 (not shown), an articulated frame (29) carries fingers (26) with tapered ends (27) which are movable, by a fluid cylinder (30), to extend into the shaft through slots in the shaft wall. Partly interleaved guides 31 are mounted below the shaft. In use, the fingers are pivoted into the passage to support wire being delivered during shearing and the guides 31 are moved together to locate the wire for blades (38), (39) on a lever 37 pivotally mounted in one of the guides.

Filed: 1974-08-01
Abstract: 1446379 Torque wrench TOHNICHI MFG CO Ltd 1 Aug 1974 [29 Aug 1973] 33917/74 Heading B3N A presettable torque wrench comprises a four-bar linkage of two members 11, 12 interconnected by links 13, 14, which is diagonally biased by adjustably pre-loaded biasing means, spring 15. Member 11 applies torque, e.g. via head 10, to a body, such as a nut, and the external force P is applied to member 12-as shown via grip tube 17 acting on rollers 19. Member 11 may have a stop 16 to limit relative movement. On application of force P, members 11, 12 tend to be urged together but are held apart by spring 15 until the torque acting on the body (nut) counteracts the pre-load on the spring and the members move. The links may be arranged so that one or both moves overcentre or a further link 18 interconnecting member 12 and tube 17 may also go overcentre. In one arrangement, Fig. 6, the links are disposed so that in the rest position cot α 2  = L(l cot α/L, which ensures that no matter where P is applied the wrench breaking point always occurs at the pre-set torque. Rollers 19 ensure that this also occurs when an oblique force P<SP>1</SP> is applied.

IPC: D04B9/26
Filed: 1963-08-28
Abstract: A three feed superpose cylinder machine has a pattern drum and selectors at each feed which are operated to effect large size Argyle patterns during knitting of a sock or stocking.  The first feeding station provides yarn for producing a diamond pattern at each side of the sock or stocking and the other two feeds have their pattern drums operated to effect diamond shaped patterns at the front and back of the garment alternately.  The pattern drums are set up to provide a pin formation with a triangular arrangement for operating a selector butts arranged in a V formation.  Two semicircular series of butts arranged on opposite halves of the selector jacks are operated from pins on the pattern drums to permit or prevent operation of the corresponding jacks thereby permitting the patterning at each of the latter two feeds to be effected.  The selectors for operating these jacks may be controlled by a lower pattern drum coaxial with the main drum but operated independently from the pattern chain of the machine whereby patterning selection can be controlled.

Title: Improvements in sound recording
IPC: G11B7/00
Filed: 1928-11-20
Abstract: 325,569. Brand, G. E., Roberts, C. W., and Roberts, A. J. Nov. 20, 1928. Optical apparatus.-Sound is recorded photographically on a film by passing a beam of light through a grid on to a mirror carried by a diaphragm which is influenced by the sound to be recorded, the beam after reflection passing through a second grid on to a uniformly moving part of the film. In the apparatus shown in Fig. 1. light from a lamp 2 in a tube 3 is focused on a grid 5, through which it passes to a mirror 6 attached to a diaphragm 7, the mirror being hinged at its upper portion to a transverse plate 24 mounted on a ring 25 which serves to clamp the diaphragm. Fig. 5. The diaphragm, to which the mirror is connected by a pin 6<a>, is held between the ring 25 and a ring 27, the latter being mounted at the junction of a tube 8 with the tube 3 by means of screws 28 associated with damping springs. To render the diaphragm aperiodic, the whole of it or an annular outer portion thereof may be made of fabric or other flexible material. Another grid 9 is fixed in tha tube 8, the grids 5, 9 being made of metal, or produced photographically on transparent material. The beam of light reflected by the mirror 6, which is vibrated by sound to be recorded, after passing through the grid 9 is focused by lenses 10, 11, on a slit 11<c> in a camera 15. Past the slit, which may be straight or V-shaped, Fig. 1<b>, a photographic film, which may be a kinematograph film, is moved uniformly, and a sound-record is thus made thereon. In a modification, the apparatus is shortened by using a number of tubes arranged one below another instead of the tubes 3, 8, light being reflected successively along the tubes by means of prisms. Figs. 6, 7 show a further alternative, in which two double prisms 16<c>, 16<d> and 169, 16<h> are arranged at one end of a tube 8, the two grids 5, 9 being also arranged in proximity to the prisms as shown. The vibrating mirror 6 is arranged at the opposite end of the tube. Light from a source 2 is reflected by a mirror 16<k> in a lateral tube 3 on to the optical system at the end 8<a> of the main tube, and by multiple reflection by the double prisms and the mirror 6, the beam is passed through both grids 5, 9. The mirror 6 may be damped by suspension in a liquid such as Canada balsam. Reference has been directed by the Comptroller to Specification 322,796.

Title: Improvements in and relating to the locking of a working piston adapted to be displaced in a cylinder by means of a pressure medium
IPC: F15B15/26
Filed: 1938-11-24
Abstract: 521,657. Locking rods. JUNKERS FLUGZEUG-UND-MOTORENWERKE AKT.-GES. Nov. 24, 1938, No. 34184. Convention date, Nov. 26, 1937. [Class 80 (iii)] [Also in Groups XXIX, XXVI, and XXXIII] In a locking arrangement of the type wherein a working piston is locked in the cylinder in which it is displaced by a pressure medium, by means of one or more locking members subjected to the influence of an auxiliary power member, particularly applicable to variable length struts for retractable landing gear of aircraft, one or more resilient expansible rings are arranged and guided in grooves in the working piston and are adapted to be maintained in locking engagement with grooves in the cylinder by one or more auxiliary pistons. In the form shown, two resilient rings 6, 7 which normally expand outwardly, are accommodated in grooves 4, 5 in the piston 2 and expand into grooves 8, 9 in the cylinder 1. The rings 6, 7 are held in the grooves 8, 9 by pins 11 which are movable radially by piston members 9<1>, 9<11> each of which is displaceable axially by a spring 10. For moving the piston 2 to the opposite end of the cylinder 1, pressure medium is admitted through port 13 to chamber 16, and passes along channels 20 to a space 18, thereby forcing the piston member 9<11> in the direction 14. The rings 6, 7 and the grooves 8, 9 are all bevelled as at 21, 22 so that, owing to the wedge action of the oblique surfaces, the axially directed force of the pressure medium on the ring 6 compresses it to such a degree that it withdraws completely from the groove 8 and the piston 2 is displaced to the other end of the cylinder 1. The resilient rings 6, 7 act as packing rings when the piston 2 moves in the cylinder 1. Instead of oblique surfaces, bell-crank levers may be used for effecting radial displacement of the resilient rings. In a modification described and illustrated in the Specification, the resilient rings normally contract inwardly.

Title: Improvements in or relating to flat bed rib knitting machines
IPC: D04B7/04
Filed: 1963-08-29
Abstract: A multi head flat bed machine, Figs. 1(a), 1(b), 1(c), (not shown), having fashioning screws 5 and nut housings H in a central control division, has electro hydraulic driving and control mechanism for operating the cam boxes.  The nut housings are associated with rollers 7,8 mounted or arms which are keyed to but slidably movable along shafts 9,10 respectively when the nut housings are adjusted. The cam boxes C are reciprocated by a bar B coupled to driven means D actuated by an hydraulic motor.  The driven means D carries cam plates 5 which at each end of the traverse engage either one or the other rollers 7,8.  In doing so the roller arm is first pivoted sufficiently to partially rotate the corresponding shaft 9,10 and thereby effect a link 13 to actuate a switch 14 controlling a solenoid which operates a braking valve influencing the hydraulic motor 6 to cause it to slow down the movement of the driven means D and thereby the cam boxes.  Further movement of the driven means then causes the cam plates 5 to further rotate the shaft 9,10 and thereby actuate a switch 19 through linkwork 24...27, or 241...271 and 28. This switch 19 controls a solenoid which operates a slide valve which reverses the motor causing the driven means and cam boxes to be driven in the opposite direction.  Further switches and valves are provided to enable the driven means to be stopped at the end of its traverse and to enable it to be driven slowly.

Title: Improvements in or relating to electrical circuits employing gaseous discharge tubes
IPC: H04Q1/32
Filed: 1934-11-30
Abstract: 436,420. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., 63, Aldwych, London.-(Assignees of Vereinigte Telephon-und Telegraphenfabriks Akt.-Ges. Czeija, Nissl, & Co. ; 75, Dresdnerstrasse, Vienna) Nov. 30, 1934, No. 34404. Convention date, July 30. [Class 40 (iv)] [See also Groups XXXV, XXXVIII, and XL] A chain of gaseous discharge tubes such as neon lamps is employed to receive impulses. The principle employed is shown in Fig. 1b, in which a current impulse through the transformer Tr1 aiding the battery B1 causes the neon lamp L to glow. A reverse impulse then reduces the potential sufficiently to extinguish L1, and the cessation of current induces an impulse in the transformer Tr2 which causes the lamp L2 to glow. Fig. 2 shows a chain of neon lamps L1-6 controlled in this manner by a reversing contact K, one lamp lighting at each reversal. The current in the last lamp lighted may control connecting or storage relays. Such an arrangement may be employed for transforming the frequency of an applied alternating current. For example, a complete operation of the chain of 6 lamps is effected by 3 impulses, so that an input frequency of 600 say operating the contact K in synchronism would give rise to an output frequency of 200 in the transformer Tr7. Fig. 3 shows a number indicator board comprising a chain of lamps L1-6 controlled by dialled impulses. An impulse through the transformer Tr7 due to the change over of a key K lights the lamp L1 by means of its control electrode E1. The first dialled impulse extinguishes L1 and L2 lights due to an induced impulse through the transformer Tr1. Subsequent impulses light the remaining lamps in turn in a similar manner.
